The Dallas Cowboys' defensive line has been underperforming, highlighted by poor performances against the Tennessee Titans and the New Orleans Saints. Derrick Henry and Alvin Kamara exploited their weaknesses, leading to heavy criticism of the team's physicality.

With deficiencies in the nose tackle position, analysts suggest that signing free agent Mike Purcell could address the issues. Mazi Smith and Linval Joseph have struggled, with low run defense grades in the early season.
